WILLIAM WALLACE: nown, or cmcmNA'r'I, omo, ASSIGNOR 'ro'rim PAPER SERVICE oonmmmor LOCKLAND, OHIO, A coaromrron or OHIO mam IJNER. 1m) rnoctsss orromme sum My invention relates to a novel type of bar- 'rel liner and to a novel method of,folding and constructed in accordance w1th my',1n-

barrel liners; i i In the art there are several distinct types of 5- barrel liners, each of which has many modifications. .Therefis in the first place a tube made from-creped paper which is open both at the top'and bottom. Secondly there is a tube made of-creped, paper open at the top only, and with a circular disc-like-portlon of crepe'd paper sewed .to the bottom. A thlrd class is] what may be called the bag type,

which is made from an inte al sheet of paper folded on itself and then stitched with 11!)" a seam along the side and at the bottom.

invention has for its object'the, pro vision of a liner of the bag typewhich may be readily inserted in a container and which will be free to expand so .as to conform to the shape of the barrel. e i. f a

The above and other objects to which reference will be made in the ensuing disclosure I accomplish by that certain combmationand rrangement of parts of which I have shown a preferred embodiment.

Referring to the drawings y Figure 1 is a perspective view of a liner of'my improved type, with portions thereof cut awa to show the internal structure and the pre erred manner in which the bag is" p the liner is designed to fit.

" I Fi ure 2i the lines A--A ixiFigure 1.

w .Figure 3 is a plan v1ew ofmy liner as itap barrel, the barrel bein concealed by the upper folded over edge 0 the liner. The liner is made from a sheet of crinkled line (if-stitching forming a side seam- 1 and another line of stitching forming a bottom closure with aseam 2. The liner prior to folding will -have the general appearance of 1 a bag which may be foldedffiat with the side edges formed on one side along the seam 1 .and. on theother by-the portion of the bag opposite. the seam 1. In folding the bag into "shape the edges of the-bag are folded" inwardly thus-forming'four lines of fold which lare indicatedat 3. The boa m come t 1 stretch of the paper is, through the infolding s a sectionaL view taken along ears to expand is enhanced by the fact that pears from above when inserted within a.

or creped paper folded over on itself witha 4 are then tucked in a 'ainst the seanr2 on the inside of the bag. en the liners folded vention are used with round barrels, which is the most frequent'use,'it' is advisable to: position the lines of fold 3 approximately one-fourth the distance from the edge seam across the bag so that when the liner is opened out it will be substantially square.

When the linersare folded, they may be readily inserted within a barrel because they are of less width than the-inside diameter of the barrel. When a liner is inserted within a barrel and material is filledin, the liner will expand without strain evenly around its entire periphery, the infolded portion gradually expanding and conforming to the' shape of the barreL. The infolding of the sides and ears is doneafter the bag is made, and the infolded ears are not secured to the bottom of the bag as in the common grocery bag, thus allowing entire freedom for eXpan-. si'on. r This is a ver desirable feature as it leaves the bottom 0 the bag free to expand around its entire periphery both be'causethe made available throughout the periphery o the bottom, and also because the free ears can open out "as required to conform to the shape of the bottom of the containerin which Furthermore, the freedom of theinfolded expand naturally-with the filling of the-con-' tamer,a sthe incoming material pressed the ears between'the'bottom'of the liner and the dering expansion.

Another advantagejin my new type of liner is that, dueto the infolding ofqthej ears on the inside of the liner, the bottom seam is '95 rough bottom of the containenfthereby .hini p i practically covered, and there is much less sewn seam exposed than with any other type of liner. This is advantageous because the sewn seams are ordinarily the weakest part of the liner and the part most subject to siftage or penetration through the needle holes.

Summing up the advantages of my new liner, it is very easy to open out because it has no folds that retard natural expansion. llt may be said to balloon out to fit the barrel. l/Vhen folded for shipment it is folded flat, and it is then of such size that it will readily slip within the head of the barrel. By malting the liner slightly wider than is necessary, the top edges may be quite readily turned down over the chime of a barrel. Finally the infolded ears cover the bottom seam and are free to expand naturally with the filling in of material into the container.

' Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is 2-- 1. A liner for a container made of readily stretchable paper formed into a flat bag, with the side edges thereof folded inwardly, and with the lower corner edges folded into the bag and against the bottom of the bag without being secured thereto.

2. A liner for a container made of readily stretchable paper formed into a flat bag, with the side edges thereof folded inwardly, and with the lower corner edges folded freely into .the bag and against the bottom of the bag,

thereby providing a liner which will be free to expand about its entire periphery.

3. A bag liner for containers, having the lower corner edges thereof folded inwardly and laid freely against the inside of the bot tom of the bag.

4. A method of folding a barrel liner so that it will be free to expand and conform to the shape of a barrel, which consists in folding the side edges inwardly and tucking the lower corner edges of the bag against the inside of the bottom thereof without securing them thereto.

5. A process of making a barrel liner, which consists in folding a sheet of readily stretchable paper and stitching the meeting edges together where the edges of the sheet meet both at the side and at the bottom, and then folding in the side edges of the bag thus formed and tucking the lower bottom corners inwardly against the inside of the bottom of the bag withoutsecuring them thereto. 6. A barrel liner of the flat bag type having a stitched seam at the bottom, with the lower corner edges of the bag folded freely into the interior of the bag so as to cover the stitched bottom seam.

7. A barrel liner of the flat bag type and with a bottom seam, having ears at the bottom of the liner folded inwardly so as to lie within the bag above the bottom seam, but unsecured thereto.

margin 8. A liner for a container made of readily stretchable paper formed into a flat bag, with the lower corner edges folded freely into the inside of the bag and against the bottom of the bag, thereby providing a liner which will be free to expand about its entire periphery.
